Slip Ring Rotor Of Induction Motor

A wound rotor motor also known as slip ring rotor motor is a type of induction motor where the rotor windings are connected through slip rings to external resistance.

Slip ring rotor of induction motor.

A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. It is a type of motor where its external circuit is connected using some rings. However the rotor construction of the slip ring motor is. If the slip motor is started with all the slip rings or the rotor terminals shorted like a normal induction motor then it suffers extremely high locked rotor current ranging up to 1400 accompanied with very low locked rotor torque as low as 60.

The working principles and stator construction of the slip ring induction motor are exactly the same as that of the squirrel cage motor. It is most widely used for industrial applications due to its self starting attribute. Adjusting the resistance allows control of the speed torque characteristic of the motor. This external circuit helps in developing a high starting torque compared to a squirrel cage type.

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. What is slip ring induction motor. Characteristics of slip ring induction motor. Wound rotor motors can be started with low inrush current by inserting high resistance into the rotor circuit.

The stator circuit is rated as same in the squirrel cage motor but the rotor is rated in frame voltage or short circuit current. Production of high starting torque with slip ring induction motor. The slip ring induction motor has two distinctly separate parts one is the stator and other is the rotor. It can improve mechanical performance simplify system operation and eliminate damage prone wires dangling from movable joints.

The rotor is wound for the same number of poles as that of the stator. As the motor accelerates. It is not advised to start a slip ring induction motor with its rotor terminals shorted. Slip ring induction motor is one of the types of 3 phase induction motor and is a wound rotor motor type.

An induction motor is an electrical device that converts electrical energy into mechanical energy. It consists laminated cylindrical core which has a semi closed slot at the outer periphery and carries three phase insulated winding. The motor which employing the wound rotor is known as a slip ring induction motor or phase wound motor.
